Technical Field

[0001] This utility model belongs to the field of children's bathtub accessories processing technology, and relates to a one-time injection molding and strong demolding mold for children's bathtub base and support feet. Background Technology

[0002] A children's bathtub is a bathing appliance designed specifically for infants and toddlers, aiming to provide a safe and comfortable bathing experience. Currently, children's bathtubs are mainly produced through injection molding. The base and support feet of the children's bathtub are important components, which are installed at the bottom of the bathtub body to support the bathtub body and ensure the stability of the children's bathtub during use.

[0003] Existing children's bathtub bases and support legs are generally injection molded using two sets of molds, which affects the processing efficiency of the base and support legs. To address this issue, we designed a one-time injection molding process for children's bathtub bases and support legs with strong demolding capability. Summary of the Invention

[0004] The purpose of this utility model is to provide a child bathtub base and support legs that are injection molded in one step with strong demolding, so as to solve the problems mentioned in the background art.

[0005] The purpose of this utility model can be achieved through the following technical solution: a one-time injection molding mold for a child bathtub base and support feet with strong release capability, including a lower mold base and an upper mold base, the lower mold base and the upper mold base being adapted to each other, support foot mold cavities being opened on both sides of the top of the lower mold base, four symmetrically arranged base mold cavities being opened in the middle of the lower mold base, a glue flow channel being opened between the support foot mold cavity and the base mold cavity, and inverted convex sliding grooves being opened on both sides of the two support foot mold cavities, with strong release sliders slidably connected inside the four inverted convex sliding grooves.

[0006] In the above-mentioned one-time injection molding of the child bathtub base and support foot with strong demolding, both sides of the bottom end of the lower mold base are fixedly provided with upright plates, the bottom ends of the two upright plates are fixedly provided with a base plate, the middle of the base plate is provided with an ejector plate, and the top of the ejector plate is fixedly installed with multiple ejector pins. The tops of the multiple ejector pins pass through the lower mold base and extend into the interior of the support foot mold cavity and the base mold cavity.

[0007] In the above-mentioned one-time injection molding of the child bathtub base and support legs, a top plate is fixedly provided at the top of the upper mold base, and an injection nozzle is fixedly installed at the center of the top plate.

[0008] In the above-mentioned one-time injection molding of the child bathtub base and support legs, square positioning grooves are provided at the four corners of the bottom of the upper mold base, and square positioning blocks that are connected as one piece are fixed at the four corners of the top of the lower mold base. The four square positioning blocks are adapted to the square positioning grooves.

[0009] In the above-mentioned one-time injection molding of the child bathtub base and support legs, four inserts adapted to the base mold cavity are provided at the bottom center of the upper mold base, and the bottom of each of the four inserts is fixed with a post hole.

[0010] In the above-mentioned one-time injection molding strong demolding mold for the child bathtub base and support foot, the surface of the support foot mold cavity is provided with multiple cross-shaped grooves at equal intervals.

[0011] Compared with the prior art, the advantages of this utility model of children's bathtub base and support foot being one-time injection molding with strong demolding are as follows: by integrating the base and support foot into one injection mold, the base and support foot can be simultaneously injection molded in one go, which effectively improves the processing efficiency of children's bathtub accessories. At the same time, through the cooperation of the sliding strong demolding blocks and ejector pins on both sides of the support foot, the base and support foot can be demolded synchronously, ensuring that the base and support foot are demolded synchronously and quickly.

Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-4As shown, the present invention relates to a one-time injection molding mold for a child bathtub base and support feet, comprising a lower mold base 3 and an upper mold base 5, which are adapted to each other. Support foot mold cavities 12 are provided on both sides of the top of the lower mold base 3, and four symmetrically arranged base mold cavities 13 are provided in the middle of the lower mold base 3. Adhesive flow channels 15 are provided between the support foot mold cavities 12 and the base mold cavities 13. Inverted convex grooves 9 are provided on both sides of the two support foot mold cavities 12, and strong release sliders 10 are slidably connected inside the four inverted convex grooves 9.

[0019] Specifically, by integrating the base and support legs into a single injection mold, the base and support legs can be injection molded simultaneously in one step, effectively improving the processing efficiency of children's bathtub accessories. like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention relates to a child bathtub base and support foot that are injection molded in one step with strong demolding. The bottom of the lower mold base 3 is fixedly provided with two upright plates 2 on both sides. The bottom of the two upright plates 2 is fixedly provided with a base plate 1. An ejector plate 7 is placed in the middle of the base plate 1. Multiple ejector pins 8 are fixedly installed at the top of the ejector plate 7. The tops of the multiple ejector pins 8 extend through the lower mold base 3 to the interior of the support foot mold cavity 12 and the base mold cavity 13.

[0020] Specifically, the ejector pin 8 enables the demolding of the molded support feet and base.

[0021] A top plate 4 is fixedly installed at the top of the upper mold base 5, and an injection nozzle 6 is fixedly installed at the center of the top plate 4.

[0022] Specifically, the setting of the injection nozzle 6 enables precise docking of the injection mold with the extrusion end of the injection molding machine body for glue injection.

[0023] Square positioning grooves are provided at the four corners of the bottom of the upper mold base 5, and square positioning blocks 11 connected together are fixed at the four corners of the top of the lower mold base 3. The four square positioning blocks 11 are adapted to the square positioning grooves.

[0024] Specifically, the cooperation between the square positioning block 11 and the square positioning groove improves the accuracy of the mold closing between the upper mold base 5 and the lower mold base 3.

[0025] Four inserts that are compatible with the bottom mold cavity 13 are provided at the center of the bottom end of the upper mold base 5, and the bottom end of each of the four inserts is fixed with a post 14.

[0026] Specifically, the setting of the perforated column 14 enables the injection-molded base surface to have multiple assembly holes, facilitating the assembly between the base and the support leg.

[0027] The surface of the support foot cavity 12 is provided with multiple intersecting strip grooves at equal intervals.

[0028] Specifically, the design of the grooved strips creates evenly distributed anti-slip strips on the surface of the injection-molded support feet, improving the stability of the children's bathtub.

[0029] In specific implementation, when using the child bathtub base and support feet for one-time injection molding with a strong ejection mold, the injection mold is first installed in the injection molding machine body, so that the electric push rod of the injection molding machine body is connected to the ejector plate 7 and the strong ejection sliders 10 on both sides of the lower mold base 3. During the injection process, the glue flows into the support foot mold cavity 12 and the base mold cavity 13 through the glue flow channel 15, realizing the glue filling of the support foot mold cavity 12 and the base mold cavity 13. After injection molding, the upper mold base 5 separates from the lower mold base 3. When the upper mold base 5 separates, the hole pillar 14 moves upward synchronously, forming an assembly hole on the surface of the molded base. Then, the electric push rod pulls the strong ejection slider 10 to move outward, so that the strong ejection slider 10 separates from the sides of the two support frames. Then, the electric push rod pushes the ejector plate 7 to move upward, and the upward movement of the ejector plate 7 drives the ejector pin 8 to move upward, so that the base and support feet are demolded synchronously, completing the injection molding process of the base and support feet.
